The PIC14C000 parts you have received conform func-

tionally to the PIC14C000 data sheet (DS40122B),

except for the anomalies described below.

USING AN1 AND AN5 AS ANALOG INPUTS

1999 Microchip Technology Inc.

Analog inputs AN1 and AN5 can not be used if

their level-shift network is disabled. According to

Section 9.2 of the PIC14C000 data sheet,

(DS40122B), the level-shift network feature can be

turned off by setting the LSOFF bit (SLPCON<4>).

However, doing so will cause the AN1 and AN5

inputs to go to V

analog input channels. Therefore, the LSOFF bit

must remain cleared. The other functions associ-

ated with these pins, such as the current zeroing

and filtering switches, operate as specified. The

AN1 and AN5 pins can still be used for ADC oper-

ations, but a small firmware routine is required to

ensure accurate results. This routine can be imple-

mented by following the steps below:

• Ensure the LSOFF bit (SLPCON<4>) is

• Ensure a good zero-level on AN1 and/or AN5

• Perform an A/D conversion as normal and keep

• Enable the signal of interest onto AN1 and/or

with either PORTC<7:6> or PORTD<1:0> to pro-

vide the clock and data signal connections.

According to Figure 7-16 of the PIC14C000 data

sheet (DS40122B), the MISC<bit 3>, SMBus bit,

allows user to select the input thresholds of

PORTC<7:6> and PORTD<1:0> to either be

SMBus-compatible or Schmitt Trigger-compatible.

Although the data sheet says that PORTC<7:6>

operates the same way as PORTD<1:0>, in the

actual implementation, PORTC<7:6> always uses

the Schmitt Trigger input thresholds when the I

module reads through PORTC<7:6>, even if the

SMBus mode is selected.

If PORTC<7:6> are read as port inputs, while the

SMBus mode is selected, the SMBus voltage levels

are used.

Interfacing to an SMBus port can still be imple-

mented using either of the following methods:

• Use the I

PORTD<1:0>, and set the MISC<3> bit high.
